If what you say is correct, I could perhaps run this setup on a 2.8 pulley? I think I would definitelly run mid 13s on a 2.8.

I can definitely drop to 3.0 now, but I'm not so sure I could run a 2.8. I guess there's only one way to find out, right?

Perhaps I could also get a 2.8 and try out at the track once I get larger injectors. Although I don't think I would daily drive on the 2.8 at all lol. But it would be fun if I could use it for the track and run 13s. Probably would need some drag radials too.

I dont see why not... I have never had much issues maxing out stock injectors on a VS cam car at 700ft.... Most cars would have 42s running at 80-85%.

Injector duty is your best gauge on how much air you are moving, not boost pressure/pulley size.

So actually, my conversions are pretty spot on,

Not really, 13.6-13.8 is pretty common for a 3.4/downpipe car at sub 700ft. Like I said he could easily run within .2-.3 of what he would run at lower altitudes with a pulley swap on the blower. I was comparing turbos because they operate very similarly to a blower that would allow you to adjust pulley size to compensate. A turbo naturally will spin faster at higher altitudes, a blower can to you just have to "tell it" to.
